“We had two samples in Lake Erie that we just kept going back and rechecking the data, because the count, the number of plastic particles in the sample, was three times greater than any sample collected anywhere in the entire world,” said Sherri Mason, the project leader and SUNY chemistry professor.
James Dau, writing for the Great Lakes Echo, reports:
They found the least plastic in Lake Superior, with the concentrations increasing as they sailed south. That’s because water flows south from Lake Superior through Lake Huron and into lakes Erie and Ontario. The water carries plastics from one lake to the next, compounding the concentration each time, Mason said.
